' whereupon the val ve the engine. in this parengine 1s started on commeans for. starting tieuiar tractor' the pressed air, which is stored in a reservoir 2 supported by cross erin 22 in brackets 23, which are connected to an axle member 24 .inwhich the stub aide 25 of each ot'- the steering wheels 12* is pivotaliy mounted. his compressed air reservoir is iocated 1n the front part of air by a small compressor unit 2G mounted in a 'space forinedin the front and lower portion of the casing or frame of the radiator 20.l This compressor unit 26 includes an. air compressor 2'? which is driven by a small gasolyene engine 2S, atmospheric air eing-drawnfinto the compressor unit space within the radiatorthroiigh a sieve'29. The

compressed air isl forced 'from the air coin-l presser 27 into the reservoir 21 through a pipe 30, the pressure of the air in the reservoir being indicated by a gage 3L' This pipe 30, extending between the compressor and ti l 32- 15, or cylinders, pipe is properly connected so that the compressed air may be forced into said cylinder, for starting purposes, the admission of the compressed air into the cyiinder l5 bein eontroiled by a hand operated valve 33. Located in the forwardend oi'' the pipe 32 is a -iaive 34, which may be closed while the compressor is4 in operation and pumping air into the reservoir 2l. This 'valve 34, however, should be kept open when lit is desiredA to start the engine lai on compressed air. starting' the power engineof the tractor, the compressed air is to be admitted to corresponding toy the power stroke;` The valve vi3 1s maintained "open,V permittingcompressed air to into the cylinder at the proper time, iintii an explosion bascociirred in the c viinder or one of thc cyiinders of the engine and said engine Started, is closed and tl1c .engine operates asiisiiai.

By placing the comi'nessor unit in tionfo theradiator traine it from ail dii'st and. would prove injurious, and at the same time occupies minimum aiiioiint ot' space and makes a neat. appearance. That part of the radiator in which the compressor unit is mounted'is provided with doors 40 (oni)7 one beingfshoiifn), by means of which said unit is accessible at ali times. pressed air reservoir a poris protected located conveniently,

t is evident that various our intention to-c'over all such which do not involve 'a departure from the spirit and scope of our invention as Set forth inthe appended claims.

What we claim as new is:

1. In a. "tractor, the combinationof a frame, a `power engineA carried thereby, a radiator for said engine 'having a casing. an air reservoir, an air compressor mounted in the casing of said radiator, and connections between said compressor, reservoir and engine.

2. In a "tractor, the combination of a frame, a powerengine radiator for said engine having a casing and being mounted. on. thefront part of said frame, an air reservoir'moiinted under said radiator, anaircompressor mounted in' the casing of said radiator, and connections said compressor, .reservoir and engine. 3. In a, tractor, the combination of a p verr engine, adapted to be started anto- ,i l ina-tical] a radiator therefor having a dust proof casing, an' air compressor located inl the casio?" of said radiator, and a connec- )en said coi-nprcssor and engine.

Iii/"ai tractor, 'the combination of a started alitoinaticai/iy/f, a radiator therefor having a dust proof casing, an air reservoir. an air com )ii-essormounted in the casing' of said radiator, 'and .connections between said com- 1p1-essor, reservoir and engine. one of the cylinders on the stroke of itspiston 5.- inl a ti'actoi"thc combination of a power engine vadapted to be started aiitosaid engine having a cbainlwr tbci'cin.'an air coiiipiessor nioiinted in Said chamber, an air reservoir mounted under said. radiator, and connections beanil engine.
